 Onion is a lightweight PHP package designed to facilitate layered processing within applications, It provides a clean and efficient way to stack layers of functionality, allowing developers to create flexible and reusable components that can be easily composed and managed.
 Each layer can perform a specific operation on the data being passed through, making it simple to build complex workflows while maintaining clear separation of concerns.
